Add download-link output

This PR adds a download-link output to the action

Fix #25

Hi! Thanks for this PR!

Do you have any documentation on how to use the output in another job? I've been trying to get it to work, but can't seem to figure it out.

Thanks.

Hey @mathisve Sorry for the delay in my answer. I've added an example to the Readme.

I also fixed the failing action. I had to update the gdrive library to 0.163 which requires go v1.20+.

The go-build action is failing again. It appears the actions/setup-go@v2 is discarding the trailing 0 of 1.20 and attempting to install the wrong golang.

Hi, sorry for the slow response (it's been a very busy time)

I've been trying out your branch in a different repository, but the output of the second step ends up being empty. Do you happen to have an example I can look at of a working github actions workflow?

Again, thank you for contributing to this repository! It means a lot to me.

All good, sure I'll setup a demo repository. I'll ping you in here when it's done.
